I think this is how many of us started at Etsy but we didn't give up in six months. We just started looking at ways to promote our shops and our artwork. If you only sit there waiting for people to find you, that rarely happens. I am constantly looking for ways to market. Heartomatic turned out to be a great way to to draw lookers to my shop. I still don't get Tweeter and think there is a lot of good information in there, I just haven't had time to read it all but I do post a few times a day, usually answers to other Tweeters and I post if I ad something to my shop or blog.
So don't quit after 6 months, just work a little bit harder. Set your goals but they are something to aim for not to live by. Of course I am sure that Donald Trump would laugh loudly at this blog but luckily he is not on my friend's list so I don't have to worry about it!
